A switch construction for use on an illuminated article worn by a user which closes a circuit providing current to an illumination source only upon the occurrence of acceleration reacting to motions of the user while at the same time limiting the amount of time the illumination source is operative, and preventing accidental continuous operation of the illumination source while the device is not in use or the body of the wearer is motionless. The switch is not gravity sensitive, and can operate in any position on the body of the wearer.

An improved switch construction responsive to the motions of a wearer comprising: a relatively fixed base adapted to be secured to desired portions of the clothing of the wearer in relatively fixed relation thereto; a substantially balanced mass mounted for pivotal movement upon said base about an axis; means for limiting said pivotal movement of said mass in at least a first angular direction; a pair of electrical contact means, at least one of which lies in the path of pivotal movement of said mass in at least one angular direction; and a source of electromotive force and an illumination means connected in series with said contact means; whereby said contact means will be closed to illuminate said illumination means only upon the occurrence of angular acceleration of said balanced mass in said at least one angular direction.
